Just recently a friend brought me this screwdriver and ask if I had one to which I replied no, haven't even seen one. He said he ran across it while out one day and thought of me and purchased it and brought it to me. How awesome is that.
Anyway it's an HD Smith #8 Winged screwdriver. They made this starting in the early 1900's and other tools in a line called "Perfect Handle".
Here is a link to a site with some information f you would like to see more.
Excited to add this to my old tool collection.
